Abstract: Described herein are methods and apparatus for the processing of electronic invoices. A server for processing invoices communicates with computing systems such as a supplier system (used by a supplier), a buyer system (used by a buyer), and finance systems (which manage bank accounts of the supplier and buyer). The server communicates with the supplier system and the buyer system regarding an electronic invoice that relates to a transaction between the supplier and the buyer, and that includes an identification code. When the buyer has approved the electronic invoice, the supplier system and/or the server is able to settle the invoice using the identification code.

Abstract: An exhaust-gas conduction component that is effective as a vibration decoupling element and can be installed in an exhaust-gas system for conducting the exhaust gases of a motor vehicle internal combustion engine. The exhaust-gas conduction component (1) has an outer pipe (2) with a corrugated metal tube section (3; 4) and an inner pipe (8) that is coaxial with the outer pipe (2) and separated from the latter by an annular gap. The outer pipe (2) also has a smooth central section (5), first and second corrugated metal tube sections (3; 4) and smooth first and second end sections (6; 7). The inner pipe (8) is permanently fixed to the outer pipe (2) by a continuous joint (9) extending around the central section (5) and the rectilinear exhaust-gas conduction component (1) is approximately axially symmetrical in relation to a central transverse axis (10). The exhaust-gas conduction component is especially suitable in utility vehicles for linking an emission control unit to an internal combustion engine.

Abstract: A wireless communication method and apparatus for recovering data following a serving cell change are disclosed. A wireless transmit/receive unit (WTRU) includes a status prohibit timer that delays the transmission of normal status reports that indicate the status of data, (i.e., PDUs), that was successfully received and/or not successfully received after a serving cell change status report is sent. A serving radio network controller (SRNC) transmits a sequence of packet data units (PDUs). The status prohibit timer is advanced and the WTRU sends a normal status report to the SRNC without a delay caused by the status prohibit timer. In another embodiment, the WTRU receives a radio link control (RLC) intelligence mode indicator signal that indicates whether a non-intelligent radio network controller (RNC) RLC operation or an intelligent RNC RLC operation is in effect, and the WTRU generates normal status reports based on the indication of the signal.

Abstract: A method and system for supporting an evolved universal mobile telecommunication systems (UMTS) terrestrial radio access network (E-UTRAN) are disclosed. The system includes a wireless transmit/receive unit (WTRU), a UTRAN and an E-UTRAN. The UTRAN sends to the WTRU a list of available radio access technologies in a coverage area of the UTRAN. The list includes information related to the E-UTRAN. The WTRU receives the list and may initiate a handoff based on the list. The WTRU then sends its multi-mode/multi-RAT capability information including the E-UTRAN capability to the UTRAN. The UTRAN then sends a measurement capability message to the WTRU. The measurement capability message includes parameters necessary for performing measurements on an E-UTRAN channel. The WTRU performs measurements based on the measurement capability message and reports measurement results to the UTRAN. The UTRAN may initiate a handoff to the E-UTRAN based on the measurement results.

Abstract: A control system (32, 75) is for use with a scanning probe microscope of a type in which measurement data is collected at positions within a scan pattern described as a probe and sample are moved relative to each other. The control system is used in conjunction with a position detection system (34) that measures the position of at least one of the probe and sample such that their relative spatial location (x, y) is determined. Measurement data may then be correlated with empirically-determined spatial locations in constructing an image. The use of empirical location data means that image quality is not limited by the ability of a microscope scanning system to control mechanically the relative location of probe and sample.

Abstract: A method and apparatus for implementing spatial processing with unequal modulation and coding schemes (MCSs) or stream-dependent MCSs are disclosed. Input data may be parsed into a plurality of data streams, and spatial processing is performed on the data streams to generate a plurality of spatial streams. An MCS for each data stream is selected independently. The spatial streams are transmitted via multiple transmit antennas. At least one of the techniques of space time block coding (STBC), space frequency block coding (SFBC), quasi-orthogonal Alamouti coding, time reversed space time block coding, linear spatial processing and cyclic delay diversity (CDD) may be performed on the data/spatial streams. An antennal mapping matrix may then be applied to the spatial streams. The spatial streams are transmitted via multiple transmit antennas. The MCS for each data stream may be determined based on a signal-to-noise ratio of each spatial stream associated with the data stream.

The control valve (VC) communicates the traction chamber (CT) with the reservoir (20) and comprises a tubular body (40) provided with at least one radial passage (41) opened to the interior of the tubular body (40) and to the reservoir (20); a shutter pin (60) to be axially displaced within the tubular body (40), between a closing position and different open positions of the control valve (VC) for communicating the traction chamber (CT) with the reservoir (20); and an actuator means (A) for axially displace the shutter pin within the tubular body (40).

Abstract: A method and an apparatus for indicating a temporary block flow (TBF) to which a piggybacked acknowledgement/non-acknowledgement (PAN) field is addressed. A method and apparatus of performing receive processing to reduce the probability of false acceptance of erroneous PANs are also disclosed. A transmit station generates a PAN check sequence (PCS) and performs a channel coding on a PAN field and the PCS. The transmit station scrambles the encoded bits of the PAN field and the PCS with a TBF-specific scrambling code. Because of the scrambling, the PCS decoding at a receive station will pass if the data block is received by an intended receive station, while the PCS decoding will fail if received by a non-intended receive station. Alternatively, the scrambling may be performed before the channel coding. Alternatively, the transmit station may combine the PAN field and a temporary flow identity (TFI) to generate a PCS.

Abstract: Methods and apparatus for reducing transmit emissions are described herein. The transmit out of band emissions in an adjacent band can be reduced while complying with existing wireless communication standards through utilization of one or more of reduced transmit bandwidth, transmit operating band offset, and channel index remapping. The transceiver can support a receive operating band that is substantially adjacent to a band edge. The transmit operating band can be offset from an adjacent frequency band, and can use a narrower operating band than is supported by the receiver. The transmit baseband signal can have a reduced bandwidth to reduce the amount of noise. The frequency offset can introduce a larger transition band between the transmit operating band edges and the adjacent frequency band of interest. The transceiver can remap channel assignments to compensate for the frequency offset such that the frequency offset introduced in the transmitter is transparent to channel allocation.

Thus the drawbacks of the prior art are avoided and an improved solution for replacement of the through bolts located under the level of the floor foundation is provided. Further, no special tooling or lifting of the frame are required which makes such replacement easy and cost efficient.

Abstract: A plurality of data signals are received over an antenna array having a plurality of antenna elements. The data signals are transmitted over a shared spectrum in a wireless communication system. A signal having each of the data signals is received over each antenna element. The plurality of data signals are grouped into a plurality of groups. The received signals of the antenna elements are matched filtered for a first group of the plurality of groups, producing a matched filtered result. Data is jointly detected of the first group using the matched filtered result. An interference correction signal is constructed using the detected data for each antenna element. The interference cancelled result is subtracted from the received signal of each antenna element, producing an interference cancelled result for each antenna element. Data is successively detected for remaining groups using the interference cancelled result for each antenna element.

Abstract: A receiver employs iterative decoding of packet data, where the packet data represents a data frame encoded with at least two logical dimensions. A logical dimension refers to a layer, or sub-layer, of a layered network architecture. Consequently, a first logical dimension of encoding might refer to error detection in a packet frame at the data link layer, while a second logical dimension of coding might refer to error detection/correction encoding at a physical layer. For example, a data frame might be divided into several packets, each with a corresponding cyclic redundancy check (CRC) value as coding in the first logical dimension, which are then transmitted with a convolutional code as coding in the second logical dimension. The receiver performs iterative decoding in the first and second logical dimensions until either i) all errors are identified and corrected or ii) another type of stopping condition is met.
